CakePHP: Model that belongs to multiple others, one at a time

Submitted by Derick Ng on 12 January 2010 - 5:12pm

I have three tables: "users", "courses" and "documents". I would like to upload documents to users as well as to courses, so I would need two belongsTo-Relations for the Document model. Some belong to one model, some to the other.

Is there a simple solution to construct these relations?

How could I set up the "add"-actions?

I know I could set up two join tables and use HABTM, but that doesn't feel right. A document belongs only to one other item. Besides, I want to be able to extend the relations to more models if neccessary.
